- Pretty much everything you need to know how to fix p0448 and p0447 on your vehicle as example 2012 Nissan Pathfinder with 4.0L V8 engine but same precision can be used for Nissan Frontier and Nissan Xterra. P0448 P0447 EVAP EMISSION VENT CONTROL CIRCUIT SHORTED OPEN. NISSAN PATHFINDER, FRONTIER, XTRERRA are very common. No more evap leaks. Basic principals can be used on most of the gasoline vehicles.
In this video you will find charcoal canister, vent valve removal and installation. How to test wiring circuit down to the vent solenoid and test vent valve solenoid as well.
DTC P0448 code means that circuit for the evaporative emission control system's vent has shorted, or that the valve for this system is stuck in the closed position.
The P0447 code is defined as EVAP Emission Control System vent valve solenoid circuit open.

Did everything you did , and I cleared the code . It came on again about 15 minutes later .. I got it to finally fill up to a full tank .. should I just clear it again and recheck or do I need to replace the charcoal canister . There was liquid in the black box when I pulled the part out
Yeh, I erased the code after the repair and it never came back again. Clear the code and check it again if it will come back. You should not get any liquid fuel inside charcoal canister. Most likely it got gas inside because vehicle was overfilled by topping off your gas tank. Canister can be clean by using low pressure compressed air, sometimes it helps.
@@PistonShack I ended up taking off the charcoal canister , it had mud stuck all inside it and water .. replaced the canister and never came back ! Thank you though , video helped millions with the install
@@ostrichofhate That's great news! I will pin your comment up make sure other viewers can see it if someone has the same problem. Cheers!
‘16 Frontier.. Nissan wanted $1200... said the evap canister is bad and they have to drop the tank. Thanks to this video I just bought the canister and the two sensors. Cost me $200 total and took me about 25 mins to change. Don’t forget to buy the pliers for the fuel hose connection.
Hi Paul! Thanks for your feedback! I am so glad it helped you out. Sorry late replay. Cheers!
Nissan wouldn't fix it under their extended emissions warranty???
@@killertofu No, it only covers a clogged tube. They did a smoke test and said the canister was bad so it wasn’t covered.
This video helped me out a bunch. I couldn’t get the charcoal canister off because the bolt was all rusty and seized. So I just took of the plastic wheel well, shoved my hand inside, and 30 mins later I finally had the valve out lol.
Thanks for the helpful video.
Thank you! This helped a lot with identifying what tools I needed and how to remove the necessary hoses and clips to drop the canister. Made it very easy!
Really interesting how you test it. Your videos are getting better and better! Ride on!
Yeah! tried one day) Thanks for watching!
You can do this without pulling the can out and without removing the evap line with the clip. Drop the can down , Disconnect all lines accept for the center evap line with the clip. You will have room to access the tabs on the vent and spin it counter clockwise and it comes right out. Make sure to put a little lube on the new o-ring, helps with installing the new vent.
I particularly liked that you tested the new valve against the old one, I still have the same code on my Nissan and it is nice to be able to watch a video like yours that covers all the bases, at this point I'm wondering if my new purge valve is actually faulty, thanks to your video I will be able to check it, great job!
Great point! How is your repair?
Purge valve is under the hood, this is the vent valve.
This is the video I've been searching for! Thank you for showing how to remove the fuel tank hose from the canister! Better than ry the car guy video for sure!!!
Glad it helped!
Thank you for such a clear repair video! Most appreciated!
Glad it helped!
Thanks for the video bro! Helped a lot! Nice looking truck!
Let me know f you have any questions) Cheers!
Thanks for the great video! Very detailed and helpful!
Glad it was helpful! Thanks for watching and subscribing)
Very detailed video, great job! Thanks for sharing.
Glad it was helpful, Scott!
Great video. Worked to fix my 2008 Nissan Frontier. I had to lube the center hose in order to get it to push back on. I had to use a code reader to clear the code after the replacement though.
Excellent Chris! Thanks for your kind feedback!
Greatly appreciate the informative video. I can’t believe how much they charge at the garage for this! I just ordered the valve now. Thank you and Happy New Year.
You're so welcome Evan! I am glad it helped you out. Let me know if you have any questions. Happy New Year to You and Your Family!
Thanks, this is a really well done video.
You're very welcome Brett! I am glad it helped you out.
Very good video...
Explained like a Master
Thanks for your helpful
You are most welcome Daniel!
I was able to replace mine without lowering or removing the canister. Great video btw. Its a real help to see it done before attempting it. Mine was a 2010 pathfinder. I did test both the old and new valves like you did. yup, the old one was NG.
I am so glad it helped you out Frank! Thanks for your feedback)
Could you please share what video you used as reference for doing this without removing or lowering the canister? Thanks
Great video, u explain everything
I appreciate that Carlos!
Is impressive thanks for the video. Now I going change my self
That's awesome Jorge! Thanks for watching and subscribing to the channel. Let me know if you have any questions. Cheers brotha!
This was very helpful thank you!

That is awesome Luis! I am glad it worked out for you.
Very interesting and clear! Nice quality picture and sound! Thanks
Great) I tried my best!
Hi guys! Thank you so much for making these. Just bought a lemon and fixed all the faults for less than 100 dollars and a few hours !
Save me 1600k truly appreciate it !
Our pleasure! Glad to hear Mark! Cheers!
Thanks for the very detailed video. I will appreciate it if you can do a video on how to test the short circuit wire on VIAS control solenoid for Nissan Murano 2005. I know my sensor is good what wire is short. I got the P0447 code. Everything else in the Evap system is either replaced with original parts or checked. I can see the smoke coming from the VIAS sensor which I replaced few times with no luck. so it's a short circuit from the wire end. A lot of people with first and second-generation Murano's and pathfinders are dealing with it. It will be very helpful if you can do a detailed video on that issue and explain what equipment is needed, where to buy and how to use it properly. Thanks again, you are a great help.
Hey brotha! Sorry for my late replay. I don't have this vehicle any longer but if you still have the same problem I can try to help you with p0447 just go over my Nissan Titan. Let me know. Cheers.
Very helphul bvideo. Thanks
Awesome) Appreciated your time!
Great video, thanks a lot. God bless you
Thank you too! I am glad it helped you out. God bless you brother!
Hi. Great video. Quick question. I have a 2016 Frontier with the same issue and I order a new charcoal canister. My new canister has white styrofoam inside all the valves. Do I need to remove the styrofoams before installation?
2006 subaru sti has very sensitive evap system do not overfill when fuel pump clicks off. I added another 25 cents after it clicked to match what i paid which was 15 dollars and it caused cel po447 . I just cleared it with an autel scan tool hope it stays clear. Ive already spent 1600 dollars on a new pcm due to a po448 and 447 corrosion issues
Hi Vivo, Thanks for sharing your experience. If you life in "Rust Belt" corrosion is a serious issue. Evap codes don't effect almost anything. Cheers!
Great thanks I can change mine now. 🙂
Glad I could help Francisco!
I have a P0456 and I think I just need to replace the o-ring in the vent control valve. Do I need to remove the canister to do this?
Where would you look next if you have no power at the connector for the valve?
Thank you
You're welcome Peter!
I have a 2015 Nissan frontier I have the same code I changed the canister and both sensors and it's still comes on the light came back on 5 minutes after I reinstalled everything and cranked it back up so what do you think it is I'm still baffled by it
I got a P0448 code today and my 2008 Xterra has been draining the battery so im wondering if this part is the culprit.
My problem is the solenoid electrical connector will not release !! What's the trick or special tool ?? I've got a 2002 Xterra with the vapor canister above the spare tire, but otherwise identical canister...tried by hand, adjustable wrench, then needle nose vice grip compressing latch and pulling, won't budge ! 😱
Thanks for the video.
My question is, can a faulty canister increase gas mileage?
I would suggest using a ground on the frame for the probing instead of the wheel stud
Thank brotha! Appreciated your time watching my vid! Cheers.
Just toook my 2009 Xterra in to my mechanic today for a P0447 code. Part number from the print out he gave me was 911-503. Doesn't look at all like the one in the video, when I looked it up on Amazon. Don't even see one that looks anything like the one in the video on Amazon's list. Looking for some guidance, any thoughts?
Thanks❤❤
You're welcome 😊
Thanks!
You bet!
Thankyou
You’re welcome 😊 brotha!
first thanks for the excellent information I did everything you did but now I can't find the problem because when I checked the old canister it works, can you give me another suggestion?
What DTC code is coming back?
I have to replace my canister. Can that white clip that is on the canister from the evap line to the canister be removed and reused or will I have to buy a new one
Hey Bryan! If the clip isn't broken I will reuse it but if you have a new one with a canister put a new one.
Hello, I need help. Nissan Path 2012 4.0... How Can I check canister. When I replaced canister's solimoid id did not help, also I have checked old solinoid and it work. I think may be it is canister, but how can I check it. I could not find any informaion.....
Hi PistonShack, what should the proper voltage be to operate the solonoid? I'm getting 9 volts at the harness going in. Is that enough to operate it or is that the beginning of my problem? I've swapped the valve thanks to your help, but it didn't fix it so I'm wondering if 9 volts isn't enough or if I got a faulty new canister valve. Thank you
Hey Fred. I looked Nissan Service Manual it doesn't give us exact voltage value but I think voltage should be around actual battery voltage but I am not 100% sure. Do you have any related DTC codes rather than p0448 and p0447?
No, those are the only 2 codes I'm getting on my system. No other codes. Thank you
@@fredrose3129 My pleasure Fred!
Can you provide a link to that special wrench you used to remove the line from the top of the cannister? I think you said you got it on Amazon for $15 but I couldn't find it. Thanks.
Yeh, that's right: Fuel Line Plier from Amazon www.amazon.ca/dp/B07M9Z49W2/ref=redir_mobile_desktop?_encoding=UTF8&aaxitk=74c100bb818e05be20aaf99485574d25&content-id=amzn1.sym.29a29880-8c3e-4ead-af52-123ee4e84f29%3Aamzn1.sym.29a29880-8c3e-4ead-af52-123ee4e84f29&hsa_cr_id=9936206480001&pd_rd_plhdr=t&pd_rd_r=00e82e24-2e75-4421-a6ec-3cc273336534&pd_rd_w=LznTc&pd_rd_wg=K6wxf&qid=1692680208&ref_=sbx_be_s_sparkle_mcd_asin_0_img&sr=1-1-9e67e56a-6f64-441f-a281-df67fc737124
Would bad Evap vent solenoid cause a gas fumes smell in the garage after sitting overnight
Thank you for your video, it is very good and very easy to understand, help me with the Link of the part that you replaced to buy it.
thank you so much
Glad it helped Omar! Take care brother!
I can't get that one hose off even with those pliers,any suggestions?
Spray little bit of wd40, press tabs and pull hose up by carefully wiggling it out.
hi I already change that part and I still have the checking engine light on .any idea what should I do.
thanks.
Hey David,
I will check few other things as well, as: 1) ground and power at the vent valve; 2) replace all rubber O-rings; 3) check hoses and lines for any cuts, cracks, splits etc.; 4) new vent solenoid could be deflective (not very common); inspect charcoal canister for any damage and gasoline leaks in; 5) check fuel cup and fuller neck; 6) check wiring harness and connector to the solenoid; 7) erase DTC to verify how fast it will get back or not. Let me know how everything is going.
Po447 on 2006 subaru sti. Intermittent problem.
I have 2013 frontier. The engine light has come on twice for awhile then turns off. Error code is p0448. If engine light is off now, can I continue driving or should ventilation valve or centroid be replaced? Thank you
I had been driving with this code for few months. I would replace vent solenoid soon as I have part. Cheers!
I have P0447 and tested power at the terminal and control valve. Both were good but still Po447, whats next?
Hey Mark. Sorry for the late respond. I hope next testing steps will help you to troubleshoot the code. Cause of the p0447 is an improper voltage signal is sent to ECM through EVAP canister vent control valve.
First, before performing an testing procedure, confirm battery voltage is more than 11V at idle. I would recommend you to find wiring diagram or service repair manual for your vehicle.
1. CHECK EVAP CANISTER VENT CONTROL VALVE CIRCUIT. Turn ignition switch OFF and then ON.
Select “VENT CONTROL/V” in “ACTIVE TEST” mode with CONSULT.
SELECT “ON/OFF” on CONSULT screen (use OBD scan tool)
Check for operating sound of the valve. Clicking noise should be heard.
2.CHECK EVAP CANISTER VENT CONTROL VALVE POWER SUPPLY CIRCUIT. 1. Turn ignition switch OFF. Disconnect EVAP canister vent control valve (3) harness connector. Turn ignition switch ON. Check voltage between EVAP canister vent control valve terminal 1. Should see battery voltage.
3. CHECK EVAP CANISTER VENT CONTROL VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT. Turn ignition switch OFF.
Disconnect ECM harness connector. Check harness continuity between ECM terminal 117 and EVAP canister vent control valve terminal 2. Refer to Wiring Diagram. Also check: Harness connectors C1, E41. Harness for open or short between EVAP canister vent control valve and ECM
4. CHECK RUBBER TUBE FOR CLOGGING.
5. CHECK DRAIN FILTER. Drain filter connected to another end of Canister Vent Valve.
Let me know how everything is going. Cheers!
Thank you for a great video but you should not have left out testing the ground as that is what is the most complicated
Great point!
Where can I find to buy those cables that you connected on the 9V battery to test the valve? What's the name of it?
Hey Gaspar. Those connector type, called electrical wire alligator clip. You can get them online cheap 20-50 for 15-20 bucks or at the store.
Can you just replace the canister itself to prevent future problems?
Hi Shannon, Charcoal canisters normally don't fail very often and last life of the vehicle. If it doesn't leak I won't replace it. Thanks for watching.
Was that a 9v battery you were using to test?
I have a 2011 Nissan Pathfinder that was throwing the same code, I did the same thing you did in the video and i cleared the codes and it's still throwing the same code, any idea why? Maybe dust in the charcoal canister?
Hey Tayler! Well, most likely you have leak at the charcoal canister, evap lines. Did you check Vent solenoid before installing? Are you getting power and ground to the solenoid?
No PistonShack I'm terrible with electronics, I don't have electrical or continuity testers.
Just did this and it probably worked?? Got water damage while mudding. Check engine light went out, but now my OBD is throwing out P0447 when it was throwing P0448 beforehand. Is this still an issue? Tried clearing the codes and removing the battery.
Battery keeps dying, can’t drive for more than a few minutes. Not sure what’s wrong…
Hi, I've got a 2012 frontier pro4x. I've had both the evap solenoid valve and charcoal canister replaced and my truck is still throwing a P0448 code. I've also taken both off and cleaned the dust out of them with air...and it's still thowing the P0448 code. Any ideas/advice/suggestions?
Having same issue with 2012 xterra. Any luck with yours?
@@MrSnowlver I traded it on a tundra...problem solved ;-)..but yes prior to that and after a little digging I figured out that the OEM EVAP solenoid valves are defective. I replaced it with an aftermarket and it resolved the code. Then it started throwing a P0442 evap leak code..hence the trade in. Hope this helps best of luck.
@@jonbrown9490 Thank you for the reply. It isn't my vehicle, but ready to suggest selling it. They haven't been able to smog/register it in months due to this code. I replaced valve and canister and it keeps coming back.
@@MrSnowlver That's what happend to me as well. I actually went through 3 valves, on the 3rd used an aftermarket and was able to clear the code. I also had to clear the permanent code twice before it stayed clear. There is also another solenoid valve up on the engine that apparently goes out as well. It's a bummer ...it's good engine and the frontier I had drove well...but there are just too many small issues that come up. Hopefully, this helps.
I know this is an old post but let me try. I work on land drilling rig and I do safety so I go back and forth between several rigs everyday I just got the code yesterday. Truck still seems to be running no issues but I won’t be able to fix it for another 6 days . Averaging about 30 miles a day. Is it going to get worse that soon or you think I can wait about a week to get it done?
Hi, Carlos! If you don't have any fault codes Evap codes alone as p0447 and p0448 shouldn't effect vehicle performance. I drove my Volvo XC 70 with same codes for over one year.
@@PistonShack awesome thanks I appreciate the info and God willing next week I’m going to use the video and save me a little money…thanks again
@@carlosa4069 My pleasure Carlos! Ley me know if you have any questions.
@@PistonShack wouldn't it spit the gas back out when pumping fuel?? How did you manage to fill up your tank during that time ?
Have this code on 2006 Nissan Sentra took it to a mechanic and change vent valve and code still shows (p0448)
Hey Shawn! Did he test the valve before installing? Valve itself could be defective. Check wiring to the solenoid when activating, you should have power and ground. With bi-directional control scanner mechanic can test solenoid operation. Plus look for any evap leaks at the canister. Do you have any other code present?
@@PistonShack Hey I appreciate your reply. Am not use what he had tested if i can remember I will just tell you the full story, First day when have the P0448 Mechanic did a smoke test and said something about Vent Control Value so i have paid and he changed it next day i was going to the car too do 55 miles so i can do inspection soon I turn the car on drove one block engine light came back on ran the code was the same code so i took it back to him and he had did something and light stayed off drove 55 miles and pass inspection i have ask him what was the issue he said he gave the ground a shock and thats when i research and when you mentioned it maybe could be the wiring but every since up to this day code still there was going to take it to a nissan dealer and see what they can do instead of going to the mechanic every other day and bill add up to dealer price...
you think it can be the ground? since he mentioned he gave the ground a shock? someone else told me to change the Charcoal canister... Bought the car recently 65k miles no damages or accident car most sat according to previous owner
Hi. I’m having the same issue. Do you have the link for part? I have the link for the tool. Thnx.
Hey,
I searched on Amazon for Evap Vent Control Valve Nissan Pathfinder 2012. Check if it fits your vehicle.

Let me know how everything is going. Cheers brotha.
PistonShack thanks man.
Is it the same for Nissan titan 2019 V-8
Hey brotha. I think so. Let me know what was different. Cheers.
Did you clear the code first or did it turn off on its own?
Hey Hamilton. I don't remember exactly but I think I cleared the code after I did repair and it never came back again. Normally after erasing the code it will come up in few minutes. Thanks for watching brotha. Take care.
Does this procedure apply to a P0455 on a 2011 Frontier?
Hi Derek. Yes, pretty much P0455 means an EVAP system leak detected at vent control valve. On video is 2012 Nissan Pathfinder with is the same platform as Nissan Frontier pick up truck.
@@PistonShack So I reinstalled the gas cap and cleared the error message, will see if it comes back.
I feel like I should pull it all off again and take a look at everything and reinstall it
What was the part number or amazon link? I've got a 2008 pathfinder 4.0

@@PistonShack Ok thanks I'm going to pull it then check it on a power supply to see if I can hear solenoid engage.disengage
@@nosajseveer Yup, check ground as well. Most likely vent solenoid valve failed. It's very common DTC on Nissans. Let me know if you have any questions.
@@PistonShack well i sucessfully bypassed the radiator and replaced the transmission computer after the radiator spilled . So this should be easy peasy compared to that. And that was my first transmission job and hopefully me last . We're 2k miles into that repair now.
I did it! 🤣🔧😤🏆🥇
Great!
when removing the swivel connector with the white tabs , the washers (4) fell out . Does anyone know what is the sequence to put them back in that connector ? they are : black 0-ring , transparent plastic washer ,yellow o-ring and blue plastic washer
Hi Vincenzo. What is the swivel connector? I checked Repair service manual, there's only vent valve o-ring . I don't see any other washers.
Check the manual: diyservicemanuals.com/nissan-pathfinder-service-repair-manuals/
I got manual from this resource.
It is the connector that comes from the fuel tank . When removing it , the washers fell out . If I had the right tool ( which I couldn’t find around my area) they might not have come out .
@@vlancelota2941 Brotha check FL-6 page Service Repair Manual - Fuel Tank Diagram. I don't see any parts as you said.
The connecter in question is connected to the Evap canister and has to be removed in order to clean out the canister or changing the canister .
It is the connecter that was removed with the orange pliers . I had no pliers and when I managed to get the connector off the canister the plastic Orings and washers fell out

Nope!
